some keys do not have expiration date. Best way I can think of is to use "get *"
(but there are millions of keys), store that and then use the TTL to see if has an expiry. If it doesn't then you set it.
Would this be the way to go?
I see a similar question here, that's not a unix command. How would I implement this in unix or maybe C#(I am using SSH Nuget package)?
